摘　　要：试验采用硫酸亚铁为絮凝剂,PAM为助凝剂对丰城某油墨厂产生的废水进行混凝预处理,原废水COD为642～750 mg.L-1,pH为6.5～7.5,色度为1 000～1 200倍,经试验确定最佳条件:初始pH为10,FeSO4投加量为2g.L-1和PAM为1 mL.L-(11%),搅拌时间为60 min,原废水经该条件处理后COD去除率达22%以上,色度的去除率达93%以上,结果表明该方法处理油墨生产废水中色度效果特别显著,对实际工程前处理有一定的指导意义。In this study,using ferrous sulfate as a flocculant,PAM as a flocculant to the Fengcheng ink factory waste water produced by coagulation pretreatment of raw wastewater COD is 642～750 mg·L-1,pH 6.5～7.5,chroma of 1 000～1 200 times,by experiment to determine the optimum conditions： initial pH=10,FeSO4 dosage of 2 g·L-1,and PAM for 1 mL·L-1（1%）,mixing time of 60 min,the original waste water treatment of the condition of COD to in addition to the rate of 22%,and color removal rate of up to 93%,and results show that the approach to waste water color ink are particularly effective in producing significant,the actual pre-treatment works have a certain significance.
